Spherical Surface Lithography Solutions

ALDI-SD Series – turn your idea into reality!

ALDI-SD series is designed for versatile semiconductor lithography applications on non-planar surface. It is capable of producing photolithography in nearly any type of surface or substrate material. Compare to conventional mask exposure system, it has a special designed stage and control system to pattern the substrate on the non-planar surface. It uses a unique exposure procedure, utilizing highly efficient semiconductor light source and a high resolution spatial light modulator to generate a clean high definition image with refined line width without stitching error. In addition, with the line edge smoothing technology, ALDI-SD can get better profile and better resolution. It can image on silicon ball diameter from 1mm to 100mm or even bigger, with resolution down to 1um.

Real time scaling and distortion compensation technology allowing dynamic adaption to scale and rotate the pattern in real time to compensate any variation cause by flatness variation for better registration performance.
